Ariane 6 is a European expendable launch system developed for the European Space Agency (ESA) and French Space Agency (CNES) and manufactured by a consortium of European companies, led by the prime contractor ArianeGroup. As part of the Ariane rocket family, it is operated by Arianespace, replacing the Ariane 5. The project's primary contributors were France (55.3%), Germany (21%) and Italy (7.6%), with the remaining work distributed among ten other participating countries.
